Patented Oct, .2, 19 1 jReferringto thedrawings-the;numeral10 designatesthe fire boxof a locomotive boiler 11 which is here shown as indicative of any form of steam generator upon which the presentinventlon can beused.

wT-he firej box is asusual-surrounded by the shell 12 which provides with the outer wall 1-3- of the boiler, the water, space 14, a water space 15 also being provided between the fr'ont walls 16-and317 .ofthe' respective fire boxand boiler. Thimbles or sleeves aS having reees'ses-2O at the upper edge thereof,

the purpose of which will presently appear. The forward reduced ends 21 of each conduitentends through the; space '15 and 'its sleeve S and is connectedfas shown in Fig. c l nteriorly threadedynipple 22.:carryL- mg in" disk or plate :23 attached upon-the outside of -.the wall 17;, the bolts "24 carried by the plate 21 being adapted toengage'the plate 25 with a suitable gaskettherebetween so as to-secure the coupling 26 in position w th itsattaching plate 27 held by the bolts with the port 30. "Mounted in each one I in the enlargement 31 thereof, is a ball valve 32 which is held above the sediment chainber 33 by means oft-he resilient spaced memhere 34,- a clean-out plug 35 being disposedto permit of access to the 1 coupling 26 and also the end of the pipe 21. Thevalve seat 36 is.providedto'receive theballidue to 'a bursting oft-he pipe 21; 3 At the oppositea nd 36 0f each member pling 26'" By these means itwill be seen that water is permitted l'the proper fcircula tion through the. coupling' and .the'ipipe 21.;into the conduit 18 where steam is.gen-

erated and permitted to ;fiow (through-the pipe 36 and the coupling 26 into the steam dome .of the boiler .Should anyl breakage occur within ,the conduit 1S thefoutlet of steam- Within the;fire-box'w ill cause the 28 to the plate -.=2,9 and for;.cornmunication of the c0uplings 26 18'is fattahed sa similarlyconstructed (3011-.

steam to flow through the respective couplings 26 and 26' so that the ball valve will be forced to close the respective ends of the pipes 21 and 36 and thus isolate the cou-- pling 18 from the rest of the generating system.

Also disposed within the fire box are the alternately disposed transverse pipes 37 and 38, the detail construction of each of which is identical but whose respective short and long legs are alternated with opposite sides of the fire box.

In each instance the terminal end of the long leg 39 is in communication with the lower end of the respective casings 26 while the short legs 40 are in communication with the upper couplings 26, these conplings 26 and 26 being identical with the construction shown in Figs. 5 and 6 and operating in a similar manner. The respective pipes 37 and 38 are so constructed so as to rest in alined recesses 20 of the supporting conduits 18 so that they are held in proper spaced relation and also without throwing any particular strain upon the respective casing 26 within the fire box.

It is apparent from the foregoing that this arrangement of steam generating tubes or pipes may be placed in the fire box of locomotive or other boilers and that a greater steaming area within the fire box will be provided without increasing the combustion area, thus producing an exceedingly economical and efiicient steam generator.

It is also apparent from this arrangement that the longitudinal and transverse con: duits may be readily cleaned or blown out by the simple removal of the clean-out plugs and that by the bursting of any one of the conduits the complete generator is not placed out of commission. I

By mounting the pipes 18 and 21 in the sleeves S as shown, the same are'readily removable without interfering with the water space around the fire box, this often being necessary when desired to renew or repair such pipes or conduits.

What I claim as new is:

1. The combination with a steam generator having a fire box and a water space,

of an auxiliary generator including a plurality of supporting conduits mounted within the fire box and having the respective ends thereof projected through to the extenor of the boiler, a coupling member -for each end of said. conduits forming anexteriorscommunicating means between the ends of the conduits and the water space of-the boiler, a plurality of supported conduits disposed at right angles to the supportmg conduits and having their ends dis- 7 posed at different levels and projecting to the exterior of the boiler, and a coupling member for each end thereof disposed exteriorly of the boiler and providing a communicating means between each end of said supported conduits and the water space of the boiler.

2. The combination with a steam generator having a fire box and a water space, of an auxiliary generator including a plurality of supporting conduits mounted within the fire box and having the respective ends thereof projected through to the ex: terior of the boiler, a coupling member for each' end of said conduits forming an exterior communicating means between the ends of the conduits and the water space of the boiler, a plurality of supported conduits disposed at right angles to the supporting conduits and having'their ends disposed at different levels and projecting to the exterior of the boiler, a coupling member for each end thereof disposed exteriorly of the boiler and providing a communicating means between each end of said supported con duits and the water space of the boiler, and a valve mounted in each coupling member for automatically closing the end of its re spective conduit due to a burst in such conduit within the fire box. I

3. The combination'with a steam generator having a fire box and a surrounding water space, of anauxiliary generating apparatus including two longitudinally disposed supporting conduits mounted within the fire box and having the ends thereof projected through the walls of the fire box and boiler, two coupling members to each .conduit attached to the outer wall of the boiler and in communication with the end ofithe conduit and the boiler, a plurality of transverse conduits mounted within the fire box and resting upon the supporting conduits, each of said transverse conduits being provided witha lower terminal extending parallel to the side walls of the fire box and projecting through the water space'to the exterior'of the boiler, a coupling member attached to the wall of the boiler and providing communicating means with the end of said conduit and the water space of the boiler, the upper end of each transverse conduit being projected through the side wall of the firebox to the exterior of the boiler, and a coupling member attached to the outer end of said conduit and forming communicating means therewith and. the steam dome of the boiler.- .Y

a. The combination with a steam generator having a fire box and a surrounding water space, of an auxiliary generating'ap paratus including two longitudinally dis- 7 posed supporting conduits mounted within the fire box and having the ends thereof 1 projected through the walls of the firebox and boiler, two coupling members to each conduit attached to the outer wall of the boiler and in communication with the end of the conduit and the boiler, a plurality of transverse conduits mounted Within the fire box and resting upon the supporting conduits, each of said transverse conduits being provided with a lower terminal extending parallel to the side Wall of the fire box and projecting through the Water space to the exterior. of the boiler, a coupling member attached to the Wall of the boiler and providing communicating means With the end of said conduit and the Water space of the boiler, the upper end of each transverse conduit being projected through the side Wall of the fire box to the exterior of the boiler, a coupling member attached to the outer end of said conduit and forming communicating means therewith and the steam dome of the boiler, and a valve mounted Within each coupling and disposed to automatically close the end of its respective conduit due to a burst thereof in the fire box.

In testimony whereof I afiix my signature.
